Question

A bag contains 3 red, 5 black and 7 white balls. A ball is drawn from the
hag at random. The probability that the ball drawn is not black, is​

Answer 1

Answer:

2/3

Step-by-step explanation:

Number of red balls = 3

Number of black balls = 5

Number of white balls = 7

Number of favourable outcomes = 3 + 7 = 10

Total number of outcomes = 3 + 5 + 7 = 15

Hence, probability = 10/15 = 2/3
